Re: switch from 2.4.24 lvm1 to 2.6.10 lvm 2 problems

Just checking: this LVM group still boots OK on other kernels?
Indeed, boots ok with 2.4.24 kernel and an initrd. Since you mentioned
lvmcreate_initrd below,
i think i made my initrd for the 2.4.24 kernel with that script!
Yeah, I get that. /dev/console seems to be there; I don't know why it
does it, but since it doesn't seem to stop anything working I grew to
ignore it.
OK. Anyway, i've entered a bug report for the mkinitrd error when lvm is
compiled into the
kernel. (Bug#293508: initrd-tools refuses to make an initrd when lvm
support is compiled,
in the kernel)
The LVM tools need a writable /etc or nothing works. When you get that
error, / is still the initrd, which is a read-only filesystem because
it's cramfs. You can either do some jiggery-pokery to make an initrd
of a different fs type which can be mounted writable, or you can do
some different jiggery-pokery to provide a writable /etc. I chose to
provide a writable /etc; see the bit after the comment '# Make a
writable /etc for lvmtab' in the lvm-init script on my site.
OK, so if i would add your script i have a chance that it works. Anyway,
is there a good reason
for the mkinitrd script to behave this way (not mounting /etc/
writeable) or can that also
be considered a bug? IMO if the script says it's able to handle lvm,
then it can be considered
a bug.
Now, I was doing a bit of aimless poking about and I discovered that
in /lib/lvm-10 there is a script called lvmcreate_initrd, with its own
man page an' all, whose purpose in life is to create initrds for root
on LVM. It might be that this would save a lot of trouble. I haven't
tried it, though, because the machine I was setting up the LVM root on
is a server which is now live (from my point of view)
Yep, i used that for the initrd of my 2.4.24 kernel. However, lvm2
doesn't provide such a script.
If people on Woody are going to have the same problems when they do
a dist-upgrade, this is going to be a lot of fun :(
Perhaps that script will perform the requisite magic?
I found a version of the script that reportedly should work with lvm2
http://poochiereds.net/svn/lvm2/
Problem is that it doesn't support modules
3) This initrd image does not support modules.
Anyway, I hope it will work. I don't know why they don't provide such a
script standard in the
lvm2 package. Since having this problem, i've seen loads of mails of
people struggling with this.
Thanks for your ongoing help, really appreciate it!

Benedict
